We consider the properties of the second order nonlinear differential equations b''= g(a,b,b') with the function g(a,b,b'=c) satisfying the following nonlinear partial differential equation \fracd2 gccda2-gc\fracdgccda-4\fracdgbcda+ +4gcgbc-3gbgcc+6gbb=0, where: (d)/(da)=(∂)/(∂ a)+c (∂)/(∂ b)+ g (∂)/(∂ c). Any equation b''=g(a,b,b') with this condition on function g(a,b,b') has the General Integral F(a,b,x,y)=0 shared with General Integral of the second order ODE's y''=f(x,y,y') with condition (∂4 f)/(∂ y'4)=0 on function f(x,y,y') or y''+a1(x,y)y'3+3a2(x,y)y'2+3a3(x,y)y'+a4(x,y)=0 with some coefficients ai(x,y).
